various classified records of the data on the' cards. In the use of such tabulating systems from time to time it becomes necessary to duplicate comparatively large groups of s. l n

Such duplica-tions have heretofore been performed by hand punching operations and accordingly have been time consuming, eX- pensive(v and ditiicult. cards which depend lupon the operators' readingA the previouslyv punched card are subject In makingsuch duplicated cards it is sometimes desirable to suppress a part of the data derived from the original punched card and, in other cases, it is desirable to rearrange lthe punched data on the new cards in a dilferent manner and in different fields and columns than that of the original cards.

It is. further desirable to provide for i automatically effecting punching of certain repetition data on the new cards and for disposing such..repetition data in any desired fields or columns thereof.

The present invention is directed to provision of a machinein which groups of punched cards and blank cards ,may be placed and which, when in operation, automatically feeds the punched and blank cards therethrough, reads the punchings of the punched cards and effects a corresponding punching of the blank cards? Provision is made for permitting the suppressing of punching of desired data derived from the punched cards and provisions are also made for ermitting the transposing of data derived -Prom a given field or column upon v the punched cards to other fields or columns upon the to bel punched cards. Provision is also made for automatically punching repetition data in any selected fields on the new cards and for suppressing certain data derived from the original cards and, if desired, impressing other data as selectively determined by a setting of the machine.

Other objects and advantages will be more fully set forth in the 'accompanying specifica- Furthermore, copied tion and claims and shown in the drawings lwhich, by way of' illustration, portray a preferred embodiment' of the invention.

punched and unpunched cards from the sup-v -ply magazine into the discharge stack. Suitable reading means are provided for sensing the perforations in the already punched cards and these reading devices selectively control the operation of punches which act upon the.

blank cards. l

In addition to the above, means, such as a plug-board. is provided to permit. the rearranging of the data derived from the original card on the new card.

-Means arev also provided for suppressing the making of perforations derived from a part of a card column and, if desired, puttingl a new designation upon the new card in they same column.

Further means are provided for suppressing the making of all perforations upon the new card derived from a particular eld of' the original card and, yif desired, a means is provided for the making` upon the new lperforation or group of perforations which repre- '1revl parts shown in Fig. 2 in moved posisent a number card.

` train, shown in Fig. 1, is adapted to' drive a reciprocatin'g picker crank 11, upper and lower feed rolls 12 and 13, and the stacker rolls 14.

'It 4will be understood that the' feedfrolls,

picker mechanism and stacker devices are uplicated, one set being provided for the punched or original cards and a second set.A for the unpunched or blank cards. Thes e parts operate concurrently.

In Fig. 3, the original cards are taken from the s ply stack 15 bythe picker and are deliver to the `feed rolls and by other mechanism are deliveredto thedischarge rolls 13 which in turn pass the cards to the stacker which delivers them to the discharge stack 16. In Fig. 2 there is shown a similar rrangement of parts adapted to deliver t 4.new or unpunched cards from the supply ocket 17 to discharge stack-or pocket 18.

Both the original and new cards in their transit from the upper feed rolls 12 to the lower feed'rolls 13 are advanced'v by a step. by ste motion in order to permit the punchingo the new cards while they are at rest.

Reading. of the perforated cards may be effected while the said cards are in motion and suchsensing or reading'controls the operation of the punches, which operation takes place at a later time in the card cycle.

.Referring to Fig. 3,` the shaft 10 carries a cam 19 having a ivot'ed follower 20 connected'to a vertica ly slidable rack-.21 enmeshing with a pinion 22 fixed to a shaft 22 carrying gears 23 which in` turn meshwith vertlcal racks 24. The stepped arrangement 4of the cam contour of cam 19 provid for a step by 'step descent of racks 24 and 'cam 19 also provides for'a quick return of the racks.

Each lrack 24 is suitably guided for vvertical l movement in the frame of the machine and carries a rearwardly extending portion which supports clip mechanism adapted to receive and the cards.

The clip mechanism comprises an anvil 25, pivoted upon spring actuated cooperating' clip members 26, said members having a locking arm 27 cooperating witha stepped latching dog-28." Fig. 'Ivshows the clips released from the locking dog and engaging the card C and holding the latter against anvil member 25. Each clip is-provided with an exftending lip 'or shoulder adapted to engage under the edge of the card to properly register the same upon the clip carriage. Release of the card and opening of the clips is efected by a cam element 29 which is adapted to engage a pin 30 carried by locking arm 27 when the clip carriage has reached its extreme lowermost position (see Fig. 10). The

clips 26, after release lowermost position, l

travel upwardl with the carriage out of the Y card path, as 1n Fig.- 10, being retained in such position by locking dog 28. Just before reaching the extremel upper position preparatory to receiving a card the clips are released by means of a fixed pin 31 carried by the frame of the machine. strikes the dog and rocks the same to release the clips.'

To ensure the. upperv cards properly engaging the clip mechanism in proper registe'r and to ensure the ejectmentof the cards into .engagement with the lower discharge.

feed rolls, I provide upper'and lower fingers .32, 33 actuated by the linkage 34-35 from cams 36-37 on shaft 38. This shaft is driven by the gear train shown in Fig. 1. 'Ihe arrangement of the linkage is such that .the fingers 32-33 are projected baclt of the rear edge of the two cards and then lowered to contact with the cards and properly position and deliver the same Upon the upward movement of the fingers which takes place upon thestep by step downward movement of the card carriage, the fingers are withdrawn rearwardly out of the path of the descending cards. 4Subsequently the fingers are elevated and Lprojected back of the tcp edges of the next pair of cards.

perforation maag devices.

This pin Disposed across the section of the machine v past which the punched cards travel is a cornmon bar 40 carrying brushes 41 and cooperatingthrou h the perforationsjin the card with contact b ocks 42. This brush arrangement is thus commonly used in tabulating machines card, are slidablycarried by a frame 47 and v impelled through the card by` means of a common actuating" bar 48.l lThis bar is slid# ablymounted in the' frameuof themachine and is vibratedback and forth bv a cam 49 cooperating with follower 50 attached to said bar. Cam 49 is fast toa'shaft 51 which is driven by gearing 52 from shaft 10 (see Fig. 2). f To'select the particular punch or punches for operation according to the energization of the selector magnets 45. selector abutment members 53 are provided whichA normally assume the positon shown in Fig. 2. Upon the energization of a' particular magnetv45 its armature is attracted and a. call `wire 55 drawn to the right, swinging pawl 56anticlockwise and releasing a T-shaped lever 57 so that a spring 58 may rock the latter and project the :acelera selector finger in between the punch and the actuating vban48.l vrll`he subsequent displacement (see Fig. 7) of the actuating bar displaces the vpreviously through the new card. Such displacement is eiiected while the card is at rest. To restore the punches pivoted fingers are provided which engage shoulders on the punches. These linger devices are actuated by a bail 61 which is directly connected to the actuating barv so as to be moved by the latter (see Fig. 7). For restoring the T-members 57 and elevating the selector fingers 53 and forrelatching the pawls 56, I provide a bell crank mem-1 ber 63 pivoted upon shaft 64 and carrying a cross shaft 65 underlyingthe T-shaped levers 57. The bell crank 63 is vibrated at the proper time in the cycle by means of a pin 66 on disc 67 fixed to cam shaft 61.` In this manner the various parts are restored preparatory to the next punchingoperation. A suitable restoring spring 68 is provided to lower the crossdrod 65l after -restoring has been comp ete g Referring now to the circuit diagr'atm (Fig. 13), it will be noted'- that two supply mains 70-71 are provided. Bar 40 is connected to the main 70. The various contacts 42 of which only three are shown are connected by suitable wires, such as 72, to plug points 73 on plug-board 43. The selector magnets in turn are wired to `various plug points 74 on the plug-board. rlfhe return circuit for the selector magnets 45 comprises a wire 75 which,v

leads to cam contact devices 76 and thence through wire 77 to main 71. The purpose of the cam contact devices 76, 7 6a is to make the circuit vto the selector magnets at such time when cards arel under the brushes and to break the circuit at other times, for example, during the interval between cards. These cam contacts are similar to those commonly. used in tabulating machines Afor this purpose.

The purpose of the plug points 73-7 4 is to permitcross-plugging whereby the data derived' from any particular field may be cross-plugged so that perforations may be made either in the lsame or a different field. Inthe dia ram the cross connection 78 indicates a direct'acrossi connection. It is obvious that theconnections may be direct across or transverse or a' combination ofv notched upon its periphery to receive a dog 83 fast to a member 84 slidably mounted upon shaft85. A clutch shifter fork 86 is fast to member' 84 and coacts with a pin clutch selected punchesI 87 splined to shaft 10. Aisuitablepinch' lever shown in Fig. l4 the pin clutch is disengaged and the locking dog 83 is engaged in the notch -in the periphery of wheel 82 thus holding wheel 8 2, sleeve 79 and slotted wheels 80 and 81 fixed against rotation. By releasingL the pinch lever 88 and shifting the parts to the notch marked 90 the pin clutch 87 is still disengaged from disc 82 but the dog 83 is disengaged from wheel 82. With this position of the'parts index wheel 82 may be turned by ,hand to any desired position thus permitting the insertion of what will be termed clothes pin clips 93 in the slots inthe wheel 80 or 81. These so-called clothes pin members `act as camming elements to open or close contacts cooperating with each wheel "br 81.l The contacts94 are those which are closed by the slugs 93 on the 80 "group of notched-wheels,

adaptedto be opened by the slug 93 on the whereas the single pair of contacts 95 are wheel'81. The position of the notches is such that the contacts 94 or 95 will be opened or closed respectively at the times when per.-

forations lin the original or punched card are passing under the sensing brushes. For effecting` such contact control during the nor# mal running of the machine the vpinch lever 88 is shifted to the 91 notch thereby'engaging the pin clutch 87 with the disc 82.` With the parts thus engaged the wheels 80 land 81 rota-te in unison with the shaft 10.

The uses to which the contacts 90, 94 are put may be best understood by referring to the circuit diagram (Fig. 13). It will be noted that contacts 94, of which only one pair is herein shown, are disposed in a circuit 96 extending from main -7 9r` to a group of plug points 97 on lthe plu board 43.` These pluvboard sockets are a apted to be selectively connected to certain of the sockets 74 which are in turn connected to the selector magnets 45. By roperly arranging the clothes pin slugs 93 t e contacts 94 will energize the selector magnets 45 at the time when they are closedl by the slugs 93. In this way` predetermined repetition data may be punched on the new cards. This data will be determined by v the set-up ofthe inserted slugs 93. It will be 9, at the extreme right there is shown, an 111-" dex point column marked 100 in which particular identifying designations are disposed. In some cases itmay be desirable where a certain index point is punched out in the original lcard to suppress the making of a like punching upon'the duplicate card. In other cases,'

closed contacts which are arranged to be.

o ned by theslugs 93.v These contacts are lsposed inthe circuit 101* leading from the extreme right hand block 42 and extendin to plug polnt position 73'^. It will be no that irrespective of the closure of circuit 101 by its brush, if contacts are o ned at the time. the card circuit is made, the circuit 101`will be entirely inactive and the selector magnet 45 will not -be operated. -Thisprovdes for the sup ressing of the perfonatmg on the new ca. irrespective of a 'perforation in' the original card. One or more'slugs 93 will be inserted dependingupon how many perforations itis desired to suppress. In case itis not only desired to suppress a perforation derived from the original card but to make anew rior-ation in accordance with the set-up o theY Amachine one ofthe slugs 93 on wheel 80 toether with its controlled contacts 94 is uti# ized. A slug 93 is inserted into one of the slots in one of the wheels 80 and the correspending circuit 96 which extends to one of t e plug points 97 is plugged up to a supplementaryplug socket 102 in the circuit 101` leading to the 'selector magnet 45. With this setting of the parts the selector magnet 45 will not receive a current impulse at the time a perforation in column 100 comes under the brush but it will receive a current impulse at the time the particular contacts 94 close. v

The foregoing construction rovides means for suppressin data derived from a perforation inl the original .card and for punching substituted data upon the new card.

While the present :invention is'particularly '.irected to making duplicate cards of a run f initial unpunched cards in certain ts the invention is not limited to suchV app 'eations. The devices employed for functions also find. utility broadly in macliines havin provision for repeating upon one card data tained from another card irrespective of whether ornot there is a run or succession of either the initially punched cardsor un punched cards. By the term-card duplicating machine it will be understood that ma' chmes areY included which do not necessarily repeat and makean exact copy of theI data Y from the initiallI punched card. VFurther-` more,`this term 1s not to be construed as a limited one directed to a machine 'which'han-- dles runs of cards whether punched or unpunched. v e
